Configuration Switches
The configuration switches determines the basic communication settings
for the Modbus interface. Normally, these switches are covered by a plas-
tic hatch. When removing the hatch, avoid touching the circuit boards and
components. If tools are used to open the hatch, be cautious.
Note that these settings cannot be changed during runtime, i.e. the gate-
way must be restarted in order for any changes to have effect.
